Definitions

  • the present invention relates to a removal device for removing air, gas or micro bubbles, particles of a contaminating liquid and/or and dirt from a liquid in a closed liquid conduit system. These devices are known in the field of the art.
  • gasses are removed from the liquid in the conduit system. These gasses generally occur as free gasses or absorbed by the liquid. This is in particular important in conduits for heating systems, but may also be important in other situations. For this purpose, gas removal devices have been developed.
  • dirt parts are removed from the liquid inside the conduit system. These dirt parts may come loose from the inner walls of the conduits. Due to the flow of the liquid inside the conduit system, the dirt particles may be held in suspension.
  • dirt parts are not removed, they may clog up the conduit system or damage certain components in the conduit system, such as pumps.
  • particles of other liquids may contaminate the main liquid in a conduit system.
  • the contaminating liquid may be lighter or heavier than the main liquid.
  • a combined gas removal and dirt removal device is known from WO97/10037 .
  • This device has a gas removal element and a quiet zone below the gas removal element. In the quiet zone, dirt should come to rest and settle on the bottom.
  • a problem associated with the device of WO97/10037 is that the dirt removal function does not work very well.
  • the liquid does not become calm enough to allow dirt parts or particles from a heavy contaminating liquid to settle.
  • the liquid has a substantial speed. This speed needs to be substantially reduced in the quiet zone, in order to allow the dirt parts or particles from a heavy contaminating liquid to settle. It is in particular difficult to remove the smaller particles under 50 microns from the liquid. Another requirement is that a substantial discharge should be directed through the quiet zone, because otherwise the part of the flow which is cleaned is too small to affect the dirt level or level of particles from a heavy contaminating liquid in the total flow.
  • the device of WO97/10037 does not succeed enough in reducing the velocity of the liquid at any acceptable resistance of flow.
  • the dirt parts or particles from a heavy contaminating liquid are substantially held in suspension and do not settle to the bottom of the quiet zone.
  • the flow of the liquid remains substantially turbulent, i.e. variable in time, which further contributes to the dirt particles or particles from a heavy contaminating liquid being held in suspension.
  • a possible solution could be to substantially increase the size of the quiet zone.
  • a device of limited size is desired in the field, for cost reasons and also because devices of limited size are more practical during installation.
  • a substantial increase in the size of the apparatus would lead to an apparatus of impractical size.
  • DE4017229 further discloses a device for removing contaminations from liquids in a liquid conduit system.
  • the device of DE4017229 also does not provide satisfactory results. Rather than to settle to the bottom, the dirt tends to be conveyed with the main flow through the device. The gas bubble also tend to be conveyed through the device, rather than to be removed.
  • the device according to DE4017229 is also quite large, which is not very practical in many situations.
  • Removal devices for removing gas and/or dirt and/or particles from a contaminating liquid are known from WO97/10037 , DE4017229 , EP0001866 , and US2007/0256964 .
  • the invention provides a removal device according to claim 1.
  • the quiet zone has a separate entrance and exit, a relatively calm and stable flow pattern is achieved. Substantially low velocities are possible, resulting in relatively effective dirt removal or removal of particles of a relatively heavy contaminating liquid and /or effective rising of gas bubbles or rising of particles of a relatively light contaminating liquid.
  • the branch flow into the quiet zone will have a different direction than a main ongoing flow.
  • the branch flow is oriented at right angles to the main ongoing flow.
  • the main ongoing flow may be oriented horizontally, while the branch flow may be oriented substantially vertically.
  • the removal device comprises both a quiet zone for dirt removal and removal of particles of a relatively heavy contaminating liquid and a quiet zone for gas removal and removal of particles of a relatively heavy contaminating liquid.
  • a single combined resistance zone may be provided for both the quiet zone for dirt removal and the quiet zone for gas removal.
  • each quiet zone has a respective resistance zone.
  • the present invention may also be used to clean contaminated liquids, wherein the contamination relates to other liquids.
  • thermal oil may be cleaned which comprises volatile components.
  • Thermal oil is used in heating systems, often in situations wherein the working temperature is above 100 degrees Celsius. In such a situation, the use of water would require high pressures and devices capable of handling such high pressures. With thermal oil, substantially lower pressures can be used in these temperature ranges.
  • US5820648 and GB2375056 disclose systems for cleaning such thermal oil.
  • these systems include a vaporisation chamber for the main liquid, i.e. the thermal oil, a condenser and other substantially complicated parts. These parts make the systems as a whole quite complex and cumbersome.
  • the present invention provides a much simpler solution, i.e. without a vaporisation chamber for the main liquid.
  • the relatively light component may a volatile contaminant in thermal oil, or a different contaminating liquid in a different main liquid.
  • the removal device comprises a quiet zone for dirt removal or removal of particles of a relatively heavy contaminating liquid, wherein the flow guides in the quiet zone define:
  • the removal device comprises a quiet zone for the rising of gas bubbles or rising of particles of a relatively light contaminating liquid, wherein the flow guides in the quiet zone define:

  • the flow guides define an entrance flow section from the bifurcation point into the quiet zone, wherein the cross-sectional area of the entrance flow section increases in the direction of flow.
  • the flow guides define one or more return flow sectional from the quiet zone to the merge point, wherein the cross-sectional area of the one or more return flow section increases in the direction of flow.
  • Bernoulli's principle dictates that a decrease in velocity results in an increase in hydrostatical pressure.
  • the hydrostatical pressure in the resistance zone is higher than in the approach zone and in the leaving zone. This results in the forming of the flow through the quiet zone, i.e. the flow enters the quiet zone from the resistance zone where the hydrostatical pressure is high. The flow flows through the quiet zone and into the approach zone or leaving zone where the hydrostatical pressure is relatively low.
  • the resistance zone when viewed from above the resistance zone comprises:
  • the resistance zone when viewed from above the resistance zone is substantially rhombic, wherein one corner of the rhombus form is substantially directed at the supply opening and another corner is substantially directed at the discharge opening.
  • the one or more resistance members are bubble-forming members which comprise a relatively large surface area onto which gasses in the liquid may attach and form bubbles.
  • the removal device comprises a plurality of return openings, wherein at least one return opening is provided upstream of the bifurcation point and wherein at least one return opening is provided downstream of the bifurcation point.
  • the removal device comprises one or more return openings, wherein the one or more return opening is only provided downstream of the bifurcation point.
